AUTOMOBILE SIGNAL.

Application led November 24 1925. Serial No.y 71,080.

This invention relates to automobile signal mechanism and has particular reference to a simple convenient and practical autoinatie means for iltulicatinnr the intent ott' the driver ot an automobile te those who are runningr uniformly no indication will be A further object of the invention is to pro,- vide improved meansl for giving an indicaL tion of a. prospective riffht or left turn, suol; means including;- devices actuated coincidentwithv the normal steering ot the wheel, or Capable of manual manipulation for a. simi- Vlar oui-'pose before the Wheel is turned.

This n'iechanism eonteifnplates also the manual manipulation of a right or left turn signal mechanism by the operators foot as Well as in the region of the steering Wheel.

lVith the foregoing; and other` ohjeetslyf-in View the inif'ention consists in the arrange nient and combination of parts hereinafter deserihed and claimed, and While the invention is not restricted vto the exact details of construction di.A

Fi Y) is a raannentsnjv View .of thespeed mechanism hut with the indiation that the .spoed is being reduced.

Fig. is a view of the speed*Controlled mechanism as iu Figs. i and 2, but with the indicatiem that the machine is 'stopped or about to stop. l I

Fig. l is a detail view part-ly in section of the steering wheel and associatedV Contact members.

Fig. 5 is a transverse sectional detail on the line 5-5 of Fig. 4.

F 1g. 6 is an enlarged detail view of the speed controlled mechanism. the parte being imposition corresponding to an acceleration of speed.

Fig. 7 is a horizontal section on the line 7-7 of Fig. 6.

Fig". 8 1s a diagnfin'in'iatie New of an automobile showing the relation thereto or improved meehanism.

Fig". 9 is a/detail et theAY manual control.

Referring noi'v more specifically to the drawings,y 1Q indicates a easing' of ani.T suitable size, Constr ietion, or design and Whieli may be located i t any convenient place. pref ,erably oneI that is Well protected from eX- ;ternal infi'i'icnces as by being` mounted upon .or Within the instru-ment vhoard 11 of a machine'.t Jouinaledtwithinthis easing' is a shaft. 12 which for' best results should he arranged vertically-'the sainelliaiiinn fixed at ,itsiuppe: end a eoliar 13 to which are.

The lower ends of the links are articulated to a. collar 16 slidahle upward and downward alone; the shaft, up Ward against the force of an expansion spring 17 siirroundingr the shaft. ancldown- Ward unde` the influence oit ,f rravitiy actingr uponthe :Weights 15. f This collar has rotatable engagement with the neck portion 18 of a carrier '119, as through one or more pins 2O so that While the collar 1G is moved upward, the carrier 19 will he moved similarly along the shaft: l2. hut the carrier is held from rotation in the casing, heine'v coniined for vertical "movements only. For this purpose the'carrier is slidahle alongr a guide 2l in the nature oi'a partition or Wall of the casing.
